Minskad miljöbelastning i framtidens byggande Björn Stigson, President of WBCSD Byggmaterialdagen Stockholm 3 April 2008 WBCSD: An overview Coalition of 200+ companies represented by CEOs Stock market value: 8,000 BUSD Supplies products and services to half of the world’s population every day Regional Network with local organizations in 60 countries 2 Byggmaterialdagen, Stockholm 3 April 2008 Access to energy is key for society Oil Biomass Gas Coal Nuclear Renewables Primary Energy Power Generation Direct combustion Industry and Manufacturing Liquids Final Energy Mobility Energy Energy Energy Buildings Consumer Choices 3 CO2 Emissions - 450 Stabilisation Case Achievable or Science Fiction? 45 Energy-Related CO2 Emissions 42 Gt CCS in industry – 3% CCS in power generation - 9% Nuclear – 13% Renewables – 20% Switching from coal to gas - 8% End Use electricity efficiency -17% Reference Scenario 40 Gt of CO2 35 30 25 End Use fuel efficiency – 30% 27 Gt 450 Stabilisation Case 20 23 Gt 15 10 2005 2010 2015 2020 2025 2030 By 2030, emissions are reduced to some 23 Gt, a reduction of 19 Gt compared with the Reference Scenario (IEA) Byggmaterialdagen, Stockholm 3 April 2008 4 Going Forward Energy and Climate a societal transformation challenge What does a society look like that emits 60-80% less GHG emissions by 2050? – “Different” – Major impacts on lifestyle, consumption patterns and infrastructures are likely – New public-private partnerships will be needed 5 Byggmaterialdagen, Stockholm 3 April 2008 Urgent Challenge The Urgent Challenge of Energy Efficiency – Buildings today represent about 40% of world’s energy demand: • 33% in commercial buildings • 67% in residential – Worldwide energy consumption for buildings is expected to grow up to 45% from 2002 to 2025. Byggmaterialdagen, Stockholm 3 April 2008 6 Drivers for site energy demand Demographics Living standards Lifestyle changes Design, technology and new equipment Climate change Byggmaterialdagen, Stockholm 3 April 2008 7 What if? (Site annual energy consumption in terawatt-hours) * 2003 level 2050 projection based on: Japanese per capita levels US per capita levels * Refers to residential and commercial (excludes industrial sites) 8 Byggmaterialdagen, Stockholm 3 April 2008 WBCSD Project: Company share a vision of Energy Efficiency in Buildings A world where buildings consume zero net energy World Business Council for Sustainable Development 9 Byggmaterialdagen, Stockholm 3 April 2008 About the EEB Vision What is zero net energy? Buildings, as a whole, generate as much energy as they use over a year Byggmaterialdagen, Stockholm 3 April 2008 10 The work plan Action Plan Project Announcement Facts & Trends Report 2006 2007 Stage 1 Scenarios Policy Modeling Recommendations 2008 Stage 2 2009 Stage 3 Assurance Group 11 Byggmaterialdagen, Stockholm 3 April 2008 Energy Efficiency in Buildings Key findings of the progress report, Sept. 2007 Low awareness of environmental impacts & value of being green. Energy efficiency is not an investment criteria. Lifestyles are not focused on energy efficiency Lack of know-how and experience for green construction Lack of financial instruments to reward energy efficiency The building sector is complex, fragmented and with no real champions 12 Byggmaterialdagen, Stockholm 3 April 2008 Life cycle energy use 13 Byggmaterialdagen, Stockholm 3 April 2008 WBCSD Energy Efficiency in Buildings Project The EEB study is built on data from countries representing 2/3 of world energy demand This reflects more than 100 billion square meters of building floor space Conclusion: Know-how & technologies available today to drive down world energy demand & reduce carbon emissions Byggmaterialdagen, Stockholm 3 April 2008 14 A complex sector Fragmentation in design and delivery acts as a barrier Byggmaterialdagen, Stockholm 3 April 2008 15 Variable interest by country Considered Been involved France 83% 27% 8% Germany 98% 67% 45% Spain 87% 28% 9% USA 83% 43% 16% Brazil 82% 27% 9% China 79% 28% 10% India 64% 13% 5% Japan 13% 5% 3% Source: WBCSD EEB Perception Study Aware 16 Byggmaterialdagen, Stockholm 3 April 2008 Environmental impact underestimated What percentage of CO2 emissions do you think buildings give rise to – directly and indirectly? 17 Costs overestimated How much do you think a certified sustainable building would cost to build relative to a normal building? 18 Behaviors of building professionals High Sceptical participant Campaigner Unengaged Uninformed enthusiast Personal know-how Low Low Personal commitment High Source: WBCSD EEB Perception Study 19 Byggmaterialdagen, Stockholm 3 April 2008 Changing behaviors High Convince why Sceptical participant Personal know-how Campaigner Educate How Educate How Convince why Low Unengaged Low Uninformed enthusiast Personal commitment High Source: WBCSD EEB Perception Study 20 Byggmaterialdagen, Stockholm 3 April 2008 Encouraging interdependence with a holistic approach Integrated Design process: Involves all participants in early design phase of the project Benefits of early integration Byggmaterialdagen, Stockholm 3 April 2008 21 Three approaches in a supportive framework 22 Byggmaterialdagen, Stockholm 3 April 2008 Urban Infrastructure A holistic approach requires integration of all parts of the urban infrastructure WBCSD work based on projects for buildings and mobility Byggmaterialdagen, Stockholm 3 April 2008 23 Consequence Buildings can make a major contribution to tackling climate change and energy use: Now is the time to act 24 Byggmaterialdagen, Stockholm 3 April 2008 www.wbcsd.org
